VRChat Priority Setter

A small console helper that sets VRChat's process priority before the game launches by writing a registry value. No game files are touched.

Features

• Elevates itself when needed, then writes the priority once.
• Keeps the UI readable in the console (VT100 colors, status lines).
• Open source, minimal footprint (few CPP/H headers).

Build

1. Open VRCHATPRIOSETTER.sln in Visual Studio 2022.
2. Select x64 + Release (or Debug for testing).
3. Build with Ctrl+Shift+B.
4. Optional: run update_project.ps1 to regenerate the project files if you move sources again.

Usage

Run the compiled VRCHATPRIOSETTER.exe as Administrator, choose a priority (2–6), then start VRChat. The change applies on the next launch.

Project Layout

• src/ – all C++ sources and headers.
• update_project.ps1 – regenerates vcxproj + filters to point at src/.

Notes

• Needs administrative rights to modify HKLM.
• "Realtime" priority is not recommended; use High for safer results.
